About Me

I have over 4 years of experience designing, programming, and testing DSP algorithms on a chip which can transmit and receive optical signals at high speeds (400 Gbps). My strongest languages in computer engineering are Python and PHP, having also experience in web development, first as a freelancer, and then later as a back-end engineer working on APIs. I have also experience leading teams as I have worked on plenty of projects as Technical Leader (software architect) and as Team Leader. I love to communicate effectively and be reliable in all aspects of the project.
